I'm not sure if you imply the price should therefore be high (because it's rare), or 0 (because it proves its inability to work as a currency).

> I always think there will only ever be 21 million bitcoins in existence ever. Ever.

So what? If I launch a cryptocurrency that will only ever mine 21 coins, how does that make it magically orders of magnitude more valuable than bitcoin just because it's more scarce.

Why is that important? Many things in this world are limited in quantity.

You know miners can just make one software update and change that right?
